Personally I think it is. It's not GREAT, but for simply having fun at the end of the day, it's doable. You might have to cram your "people ballast" pretty close together and be sure to have an appropriately sized board and you'll be set for fun. The attached picture is behind Ed Geary's Moomba Outback with two sac's totaling maybe 600 lbs of ballast, 5 people and in 10 foot deep water. Notice I am on an Inland Red Tide - BIG BOARD
